相关源码：

copy的文档中源码 稍加改动

import com.baomidou.mybatisplus.mapper.MetaObjectHandler;
import org.apache.ibatis.reflection.MetaObject;

import java.util.Date;

public class MyMetaObjectHandler extends MetaObjectHandler {

    @Override
    public void insertFill(MetaObject metaObject) {
        Object fieldType = getFieldValByName("gmtCreate", metaObject);//mybatis-plus版本2.0.9+
        if (fieldType == null) {
            setFieldValByName("gmtCreate", new Date(System.currentTimeMillis()), metaObject);//mybatis-plus版本2.0.9+
        }
    }

    @Override
    public void updateFill(MetaObject metaObject) {
        Object fieldType = getFieldValByName("gmtModified", metaObject);//mybatis-plus版本2.0.9+
        if (fieldType == null) {
            setFieldValByName("gmtModified", new Date(System.currentTimeMillis()), metaObject);//mybatis-plus版本2.0.9+
        }
    }
}

spring中Mybatis的配置文件

        <bean id="sqlSessionFactory"
		class="com.baomidou.mybatisplus.spring.MybatisSqlSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<property name="configLocation" value="classpath:xml/mybatis-config.xml" />
		<property name="typeAliasesPackage" value="com.zx.test.entity" />
		<property name="mapperLocations" value="classpath:com/zx/test/mapper/xml/*Mapper.xml" />
		<property name="plugins">
			<array>
				<!-- 分页插件配置 -->
				<bean id="paginationInterceptor"
					class="com.baomidou.mybatisplus.plugins.PaginationInterceptor">
					<property name="dialectType" value="oracle" />
				</bean>
			</array>
		</property>
		<property name="globalConfig" ref="globalConfig"></property>
	</bean>

	<bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">

	</bean>

	<bean id="globalConfig" class="com.baomidou.mybatisplus.entity.GlobalConfiguration">

        -->
		<property name="idType" value="1" />
		<!-- Oracle需要添加该项 -->
		<property name="dbType" value="oracle" />
		<!-- 全局表为下划线命名设置 true -->
		<property name="dbColumnUnderline" value="true" />
		<!-- 公共字段填充处理器 -->
		<property name="metaObjectHandler" ref="myMetaObjectHandler" />
	</bean>
	<!-- 自定义处理器 -->
	<bean id="myMetaObjectHandler" class="com.zx.test.common.config.MyMetaObjectHandler" />

数据库实体对象中问题字段配置

    /**
     * 创建时间
     */
	@TableField(value = "GMT_CREATE",fill = FieldFill.INSERT)
	private Date gmtCreate;
    /**
     * 更新时间
     */
	@TableField(value = "GMT_MODIFIED",fill = FieldFill.INSERT_UPDATE)
	private Date gmtModified;

目前这个问题尚未解决~，具体原因还待查。

如果有人遇到同样问题，请赐教。
